Title: Treatment of solid containing material derived from effluent
Inventor: PHIPPS JONATHAN STUART
IPC: C09D7/12
Filed: 1997-03-20
Abstract: A method is described for the treatment of a solid containing material obtained from effluent from an industrial plant or process, eg. a plant for the de-inking of waste paper.  Such effluent comprises an aqueous suspension of solids comprising organic material and inorganic particulate material.  The inorganic particulate material contains a substantial amount of calcium carbonate and is likely also to contain kaolin or metakaolin.  The solids may also contain carbon particles. The method includes subjecting the solid containing material to a heat treatment process such that the temperature is controlled to be maintained in the range 600°C to 800°C preferably 600°C to 750°C, to cause burning of the organic material without decomposition of more than about 50% by weight, preferably not more than about 10% by weight, of the calcium carbonate present to produce a particulate calcium carbonate-containing inorganic material substantially free of organic material.  The particulate product is preferably white and useful as a pigment or filler material, eg. in paper making.

Title: Double flanged roller system
Inventor: DISSEGNA ALDO
IPC: B60B1/04
Filed: 1997-04-17
Abstract: Known hubs for spoked wheels typically include a cylindrical hub shell with a flange disposed at each end, each of which has a plurality of spaced apart holes through which elbow spokes are drawn and secured by means of their enlarged heads. In this invention, individual elbowless spokes thread into, or pass through, a corresponding number of individual pivoting rollers mounted in a double flange disposed at one or both ends of the hub shell. The pivoting action of the rollers permits each spoke to follow the straightest possible path to its fitting hole on the rim.

Title: Information on hold telephony service
Inventor: FARFAN DANIEL J
IPC: H04M7/00
Filed: 1997-07-10
Abstract: An on hold telephone service that allows a subscriber to the service to place a call on hold and make information services available to the party placed on hold.  The on hold service can be implemented on a central office switch or an enhanced services platform connected to the switch.  The on hold service is accessed by the subscriber to the service through a transfer function that causes the call to be maintained by the on hold service.

Abstract: The present invention relates to compressable polymeric foam materials useful as insulation. These polymeric foams are prepared by polymerization of certain water-in-oil emulsions having a relatively high ratio of water phase to oil phase, commonly known as "HIPEs". The polymeric foam materials comprise a generally hydrophobic, flexible or semi-flexible, non-ionic polymeric foam structure of interconnected open-cells. The foam structures have: (a) a specific surface area per foam volume of at least about 0.01 m2/cc; (b) an expanded density of less than about 0.05 g/cc; and (c) a ratio of expanded to compressed thickness of at least about 3:1; wherein when the foam is compressed to 33 % of its original expanded thickness and is thereafter maintained without artificial restraint on its surface, said foam will reexpand by no more than 50 % after 21 days at ambient temperature (22 ~C). In a preferred embodiment, the foams of the present invention, when heated to their Tg or higher, will reexpand to 90 % of their original thickness within about 1 day or less. The invention also relates to a process for making the compressible polymeric foam material comprising polymerizing a water-in-oil emulsion having a volume to weight ratio of water phase to oil phase in the range of from about 20:1 to about 250:1.

Abstract: ABSTRACT A pulverized fuel combustion burner applied to a boiler of a thermal power plant or chemical plant, a furnace of a chemical industry or the like is provided in which, even if the injection direction of the primary air nozzle changes upward or downward, a proper concentration distribution of the mixed flow of the pulverized fuel and the earner air can be obtained at the exit plane of the furnace side wall and leakage of a portion of the combustion auxiliary air into the furnace is not caused. The pulverized fuel combustion burner comprised a rich/lean flow separator provided at or near the jointed portion between the primary air nozzle and the pulverized fuel supply pipe. The rich/lean flow separator is enabled to change its direction in response to or independently of a change in an injection direction of the primary air nozzle. Thus, the rich/lean flow separator follows the change of the direction of the injection of the primary air nozzle and the mixed flow so separated rich and lean can be injected in the same direction as the primary air nozzle without any biasing.

Title: Photosensitive composition
Inventor: URRUTIA DESMAISON GONZALO
IPC: G03F7/039
Filed: 1996-11-27
Abstract: The invention relates to photosensitive compositions capable of being developed as positives. Conventional compositions are either insufficiently photosensitive or unsuitable for use on copper surfaces such as those in printed circuit boards, since the exposed regions of the composition layer cannot be completely removed during development and create problems in the subsequent metal-coating or etching operations. These drawbacks are not found with the claimed photosensitive compositions. Various compositions are described containing photo-acid generators and a polymer resin containing acid-cleavable side groups and formed by polymerisation of at least three different acrylate or methacrylate monomers.
